Wise Guy eh? Why I otta! I replaced a butt load of chain/sprockets under warranty as a n00b. Low tech really. The bolt on the sprocket is like a cymbal, called a Belleville washer in aviation anyway. Wikipedia
The singles use a bend over lock tab.
So not to blame anyone, over 40k kms without checking the bolt for tightness??
For shame! Sprocket hooked? Oops, forgot to look!
Must've been "Procrashtinating!"
